How to find config error?

Configuration

Hi,

I am getting this error on Hass.io startup. Everything works … But this error is making me crazy
Can anyone push me to the correct direction how to solve it or how find what is causing it?

Error doing job: Task exception was never retrieved

Not sure, but i assume a value_template (maybe template sensor) that converts a value (float) from an entity that needs some time on startup.
Check your config for

... | float ...

I could also be wrong with this!

Thank you for suggestion. I found 5 entries with this function … comented them out … but no luck, error still shows up in log

Do you have NoneType in your configuration anywhere?

I think I found what you meantioned. I mean entity that on startup has ‘null’ value.
last_triggered has ‘null’ value
Is there a way to avoid it?

'{{ (as_timestamp(now()) - 
 as_timestamp(states.automation.restart_ffmpeg.attributes.last_triggered))
      >5}}'

Yes!

{% if states.automation.restart_ffmpeg.attributes.last_triggered %}
  {{ (as_timestamp(now()) - as_timestamp(states.automation.restart_ffmpeg.attributes.last_triggered)) > 5 }}
{% else %}
  False
{% endif %}
